1. Collecting Specimens<\/h4>\n

1) Specimens with compositions classified: Randomized specimen collected from a box of mixed down clusters and feathers, classified.<\/p>\n

2) Specimens with no composition test passed: Randomized specimen collected from a box of 30g-down clusters and feathers, by 1g from Top \/ Middle \/ Bottom layers of the box<\/p>\n

 <\/p>\n

2. Test of Identification<\/h4>\n

1) For Down Clusters<\/p>\n

\u2460 Collect randomly (to have both large and small clusters) a total of 50 down clusters out of a box.
\n\u2461 Remove alien substances by shaking the collected down clusters in the air. This will improve test accuracy.
\n\u2462 Identify using analyzer or microscope, and put the down clusters in a beaker.
\n\u2463 Remove unidentifiable down clusters, and collect again as many down clusters out of a box.
\n\u2464 If 7 or more duck downs (14+%) are identified, repeat \u2460 to have a total of 100 down clusters identified.<\/p>\n

2) For Feathers<\/p>\n

\u2460 Collect randomly (to have both large and small feathers) a total of 20 feathers out of a box.
\n\u2461 Perform \u2461 through \u2463 of the test of identification for down clusters.
\n\u2464 If 4 or more duck downs (20+%) are identified, repeat \u2460 to have a total of 40 feathers identified.<\/p>\n

 <\/p>\n

3. Representation of Results<\/h4>\n

1) For specimens with compositions classified (1-1): Results for both down clusters and feathers for goose down, duck down and chicken feathers, exclusive of residues, immature down clusters, fibers, chicken feathers and damaged feathers.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t
